JAMESTOWN, N.Y. -- Chautauqua County authorities are looking for more information about four men that they believe killed a Carroll, N.Y., couple in a home invasion Wednesday morning.

Gordon Skinner, 66, and his wife, Joyce Skinner, 59, were found by police and firefighters responding to a report of fire at the couple's home on Wheeler Hill Road in Carroll, southeast of Jamestown, at 9:22 a.m. Wednesday, Chautauqua County Sheriff Joe Gerace said.

The couple's deaths were ruled homicide, but authorities have not yet said how the couple died.

Four suspects are in the Chautauqua County Jail awaiting arraignment on charges related to the killings, Chautauqua County District Attorney David Foley said. They are Davide Coggins, 34, no address known, and three Elmira, N.Y., men: Joshua A. McCormick, 21, Steven W. Todd, 18, and Ricky L. Knickerbocker, 18.

The men were taken into custody in Elmira early today, authorities said, and are believed to have been in Carroll late Tuesday night and early Wednesday morning. Police described their vehicle as a gold 2003 Pontiac Grand Am.
